cinelerra (GNU/Linux Video/Audio Studio)

Cinelerra CV is the most advanced non-linear video editor and compositor
for Linux. It does primarily 3 main things: capturing, compositing,
and editing audio and video with sample level accuracy.

NOTE: Patches for ffmpeg-2.x from the official website are included in
this SlackBuild. These patches work for the most part, but in various
cases (like loading multiple DNxHD files) they make the program very
unstable.

If you still want to build with ffmpeg-2.x, pass "EXTERNALFFMPEG=yes"
on the command line.
